Browse duplex house plans and facades by Dhursan Construction, designed so two homes share one Sydney block without either side feeling like the leftover.
A duplex lets one block do the work of two. You can live in one side and rent out the other, keep extended family close while giving everyone their own front door, or hold both homes as investments. Dhursan Construction designs and builds duplexes across Sydney, from new estates in the South West to established streets in Western Sydney.
Every design below can be adjusted to suit your land. Our design team adapts each plan to your block’s width, slope, orientation and council controls, so both sides get practical layouts, good natural light and a clear separation from each other. If none of the plans suits, we can design a duplex from scratch.
Already own an older house on a good-sized block? A knockdown rebuild can replace one ageing home with two new ones on land you already own.
Browse our duplex house plans below, each shown with the details you need to check it against your block. Looking for something larger? See our 8 bedroom duplex designs.
Floor areas and lot widths are a guide. Your final design depends on your survey, council controls and the changes you choose.
Dhursan Construction is a locally owned, licensed Sydney builder. As duplex builders in Sydney, we handle your project from start to finish: one team checks your block, designs both homes, prepares the approval documents and builds both sides under one contract. You can start from one of our pre-designed plans or a fully custom design. Working across Western Sydney, we design around the lot sizes, frontages and council controls you’re likely to find on local streets.
Duplexes sit alongside our dual occupancy and double storey home designs. If your block could suit more than one option, we can compare a duplex, a detached dual occupancy and a double storey home with you before you decide.
Every duplex we build comes with a choice of inclusion packages, so you can match the finish to your budget and to how you plan to use each home. Compare the options below, or talk them through with us at your consultation.
A contemporary finish for everyday living, covering the essentials of a quality new home.
Hand-selected upgrades designed with modern interiors in mind, for added style and value.
A well-rounded selection of features and finishes to complete your new home.
Optional upgrades for when you want to take a room, or the whole home, a step further.
We design side-by-side duplexes in single and double storey layouts, and front-and-back dual occupancies where the block suits. You can choose one of our pre-designed duplex plans and adapt it, or have our design team create a custom design.
It starts with a free site assessment of your block’s size, frontage and planning controls. Our design team then develops a duplex concept around your land and goals. Once the design is settled, you receive detailed pricing and an HIA building contract, and we prepare and lodge the documents for approval as a CDC or DA, whichever suits your property.
Yes. Each of our pre-designed plans can be adjusted to suit your block and how you plan to use each side, or we can design a duplex from scratch. Many owners keep both sides similar to manage cost, but each side can have its own layout if that suits you better.
It depends on where your block is. In NSW Low and Mid-Rise Housing areas, the state sets a minimum lot size of 450 m² and a minimum width of 12 m at the front building line for dual occupancies. Elsewhere your council’s own minimum applies, and these vary between councils. We check this for your exact block during the site assessment.
Close, but not quite. Dual occupancy is the NSW planning term for two homes on one lot, either attached or detached. A duplex is the everyday name for the attached version. Learn more about our dual occupancy homes.
Yes. Depending on your property, a duplex may be approved through a Complying Development Certificate (CDC) or a Development Application (DA). Some controls, such as flooding, may rule out a CDC, so we confirm the pathway early. We prepare the documents and manage the application for you.
Yes, if your block meets the lot size and width rules and the design gains approval. Our knockdown rebuild service covers demolition through to handover of both homes.
It depends on your property. Subdivision is a separate legal and approval process from building the duplex. It involves survey plans, a Subdivision Certificate and registration with NSW Land Registry Services, and it can only go ahead where the site is suitable and approval is granted. We coordinate the building works and help with the pathway. Specialist consultants may also be needed. In some cases registration continues after handover, depending on your approval conditions.
